Are SanDisk SSD reliable?

As per my experience, SanDisk SSDs are generally considered reliable for everyday use and have been widely used across consumer and professional setups. However, in recent years, there have been increasing reports—particularly involving SanDisk Extreme and Extreme Pro portable SSDs—where users experienced sudden data loss or drives becoming unreadable. Western Digital (SanDisk’s parent company) acknowledged these issues and released firmware updates to address them. If you’re using one of those models, it’s essential to update to the latest firmware and avoid using affected production batches. As for critical data storage, it’s wise to always maintain a secondary backup, regardless of brand, since no drive is immune to failure.
